[PATCH v3 2/8] dt-bindings: extcon: qcom,pm8941-misc: Add PM8921 compatible

From: Alexandre MINETTE <[email protected]>

PM8921/PM8821 provide USB ID detection through the PMIC USB block. The
USB_ID_IN interrupt is exposed by the PM8921 interrupt controller and is
used by APQ8064 platforms for OTG role detection.

The device is modeled as a child of the SSBI-connected PM8921 PMIC.
Unlike PM8941, the downstream PM8xxx misc device is not instantiated with
a register resource for this path, and the mainline extcon driver only
needs the named USB ID interrupt. Allow qcom,pm8921-misc without requiring
reg.
